Performance - System Memory Perf: DDR4 Memory Read / Write

Performance System Memory: Memory Read Test

The Intel Kaby Lake-X platform supports dual-channel memory, the Skylake-X platform quad-channel. New is a bump in memory speed support. Most X299 motherboards will support XMP memories in the 4 GHz domain. Considering we are giving the AMD Ryzen platform the advantage of 2933/3200 MHz memories, we do the same for Intel. We test at 3200 MHz, in this case with quad-channel memory. Memory frequency support was a little tricky (at this time) on X299. The 3200 MHz on occasion would not boot up or the motherboard would hang with an 'OC error'. The BIOS used however was very beta. But when it worked, it worked fine though. Quad channel is a little shocking when you look at bandwidth, read performance breached the 80GB/sec marker with 50 GB/sec writes.

What about even faster memory?

 
I also popped in a G.Skill 3600 MHz RGB Quad Channel memory kit, just for fun. The faster DIMMs offer little to no gain in performance really, but the results sure look nice. The MSI board was a little faster again, likely due to P states. We are testing on early hardware and thus BIOSes though.
